Melanotan I

Melanotan I is a melanocortin peptide analogue associated with research on alpha-MSH signaling. In the published literature, the name is used for a modified alpha-MSH sequence that has been examined as a molecular probe in melanotropin research.

Research context

The foundational work investigated how changes to the peptide sequence influenced enzymatic degradation and activity in laboratory models. Its measurements included adenylate cyclase activation and tyrosinase activity in cultured melanoma cells, allowing the researchers to study distinct biochemical responses.

That research illustrates a general structure-activity question: how can small sequence changes alter a peptide’s behavior in a defined experimental system? The measurements describe the published research models, rather than a cosmetic or therapeutic application of this listing.

Sequence-modification studies of alpha-MSH analogues examine how replacing individual residues changes resistance to enzymatic breakdown and the pattern of receptor activation. These comparisons are structure-activity research in the strict sense: each analogue is a controlled variation on a reference sequence, and the measured differences describe the experimental models used.

Quality, Purity and Documentation

Review the analytical documentation listed for the selected size. Reports describe the samples identified in them; they do not by themselves confirm that current stock matches those samples. If no matching report is listed, contact Prestige Peptides for documentation before ordering.

Planned format

Melanotan I 10mg is planned as a lyophilized (freeze-dried) powder in a sealed 10mg vial. Lyophilization removes water under vacuum at low temperature, producing a dry preparation suited to controlled laboratory storage. This listing is pending release; the notification form on this page registers interest for availability updates.

Storage and handling

Store lyophilized vials at -20°C or below, protected from light and moisture. Allow sealed vials to equilibrate to room temperature before opening to limit condensation inside the vial. Once opened, handle with clean laboratory technique, minimize exposure to ambient humidity, reseal promptly, and record the lot number in laboratory documentation for traceability.
